The Winspace Zero SL is an integrated carbon handlebar and stem specifically designed for Winspace frames such as the T1550 (1st and 2nd generation), Agile, SLC3, C5, and C5 Aero. Its one-piece construction optimizes aerodynamics, provides stiffness, and allows for fully internal cable routing, ideal for electronic shifting and a clean cable layout.

Advantages
-
Optimized aerodynamics : integrated design that reduces wind resistance and improves speed performance.
-
High stiffness : the carbon construction provides a powerful response, especially useful in sprints and sudden changes.
-
Internal cable routing : allows for a very clean aesthetic and minimizes cable exposure, ideal for mounting electronic shifting.
-
Variety of sizes : multiple stem lengths and handlebar widths to adapt the position to each cyclist.
-
Compatibility with various Winspace frames : fully compatible with the T1550 and other models of the brand.
